Also I love how I can baffle it by wrapping a water bottle around sideways to where the water trickles down the water bottle instead of flowing out of the sides. This makes it seem like there is absolutely no current in my tank at all!

That's great! This is a powerful filter... haven't used one in a long time.
You might want to cover the bottom with some silter sponge because your betta's fins can get shredded there.
About 3 years ago had a betta who loved getting in between this filter and the wall of the tank... the filter sucked up his fins and shredded them.
